IMPROVEMENT IN SPARK-ARRESTERS'FOR LOCOMOTIVES.

Specification forming part of Letters Patent No. 143,66 fl, datedOctober 14, 1873; application filed August 27, 1873.

To all whom it may concern:

Be it known that I, MICHAEL BRASSILL, of

Hartford, in the county of Hartford and in the State of Connecticut,have invented certain new and useful Improvements in SmokeSta cks forLocomotives; and do hereby declare. that the following is a full, clear,and exact descrip employment of an inverted concave corrugated cone incombination with the peculiar construction of the smoke-stack of anengine, as will be hereinafter described.

In the annexed drawings, A represents the smoke-stack of an engine orlocomotive, D an d D being the head of the same, the two portions of thehead being in the form of truncatedcones with theirbases connectedtogether. In the top of the smoke-stack is placed a wire screen, E. B Brepresent three or more rods of metal, provided on their upper ends withscrew-threads, which project upward from the body of the stack and intoits head. These rods support an inverted concave cone, which is providedwith a series of corrugations, w a: 00. These corrugations are so formedthat their edges are sharp and project slightly downward. This cone canbe made of metal and hollow, so that it will not be too heavy. It can beadjusted to or from the mouth of the body of the stack.

In the use of this device it will readily be seen that when the sparksand Cinders fly up the stack they strike with force against the' edgesof the corrugations on the cone and are cut or broken, and thendeflected against the sides of the head of the stack, and then againstthe wire screen. Thus it will be seen that, by the time they pass awayfrom the stack, they are reduced to powder, or broken up into such finepieces that they cannot do any damage by communicating fire tosurrounding objects.

a. a represent apertures in the stack, which allow Cinders or trash topass down the stack again when they lodge below the mouth of the stack.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

' The combination, with the head D D, of the smokestack A, havingopenings 60 a, rods B B,adjustable deflector G, with corrugations 00 m,and the screen-E, all constructed and arranged substantially as and forthe purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this13th day of August, 1873.

MICHAEL BBASSILL.
